INSULATING-BLOCK FOR BUILDING PURPOSES.

Patented Dec. 8, 1908 Application filed. October 2a, 1906. Serial No. amass.

To all whom it may concern:

Be it known'that 1, JOHN E. Hown, a resident of the city and State of New York, have invented certain new and useful Imrovements Relating to Insulatmg-Blocks or Building Purposes, of which the following is a specification, accompanied by drawings.

and fitted where required, can be securely fastened. to studs or sup orts either of wood or metal, orcan bebui t up into a partition, wall, orother structure, without such sup.- ports, and which presents a flat surface for I 'plastermg. 25

Further objects of the invention will appear in the specification and be pointed out in the claims.

In the drawings, Figure 1 is a horizontal section, partly broken away, of a block embod ing my invention; Fig. 2 is an elevation of t e same. section lane shown in Fig. 1, showin a mode of oinin two blocks; Fig. 4 is a pan view of a mo ifiedform of block. Fig. 5

shows in horizontal section a further modified form of block, together with the mode of securing it to a wooden stud or floortimber. Fig. 6 is adetail of Fig.1 on a larger scale. 7 p

Figs. 1, 2, 3,, and 601 the drawings show a:

block composedfof a plurality of lates or layers 12 and 13 formed prefera ly of a plastic material, as plaster of paris,cement or the like. The outer plates on their inner faces and the inner plates on both faces have aplurality of dovetailed projections 16 having flat faces 17. The inner plates 13 have these'projections arranged in staggered relation on opposite faces of the plate. Each of the plates has .these projections 16 located to register with the corresponding rojections on the adjacent plate. Each p ate on thesides havin pro'ections 16 is covered with a sheet 20 0? st paper or fabric, adboring closely to the entire face of the plate,

Fig.3 is a vertical section on including the projections, as shown. Between the opposing pairs of projections 16 are placed one or more layers of fibrous material 22, which may be felt, fiber, soft a-per or the like non conducting material. i referably also a sheet of fibrous material 23, as stifi heavy paper, is inte osed tgroughout the entire length and wi th of t e togeizher in any-desired manner, as'by rows of stitching 24, forming an integral block which may be of any conveniont size, a. 9. 12x16 inches face measurement.

In manufacturing such blocks as above described, 1 preferably take 'two of the sheets 20 and secure them at either side. of the sheet 23 with the interposed strips or layers of felt 22 and sew or rivet them together as at 24 in Fig. 6. The next step after having made a sufiicient number of these composite structures is to sup ort them so that they form molds between t em for the plastic-mass of the layers 13. The plastic mass after it has been poured in and set, coin letes the structure with the exce tion 0 the outer la ers 12, which may be eit er separately app 'ed or applied at. the same time as the intermediate layers by means of a suitably shaped mold.

By reasonof the materials employed, each of which .has a marked sound and heat insulating qualitygand by reason of the large number of smallair spaces formed and also perhaps because there are no lines or lanes of material directly across the block, t e insulation securedby even a relatively thin Wall of such blocks is highly efficient. This advantage is robablyincreased by the dissimilarity of t e. materials in'contact. The blocks are of substantial strength sothat they \willstand shipment.

Where the blocks are to be built into a partition having vertical metal studdin I may provide wires 27 which are embedded in the masses of plaster and have ends projecting therefrom at each end of the block so that they may be twisted or tied around the stud.

Fig. 3 of the drawings shows a mode of construction of the blocks with rabbeted edges which enables them to be more readily and accurately alined. The ed es of the .blocks 11 are rabbeted at'28, so t at certain of the plates 13'extend beyond the others,-as shown. This facilitates the alinement of the faces of the blocks when erected.

ates 12' and 13. The parts are held- The blocks may be used in'the same way as the plaster blocks are now used. Their outer surface should be rough enough to correspond with a scratch coat of plaster so that after the blocks are laid up in the wall, referably without cement between them, 1 t e brown coat and skin coat can be applied, making the finished wall or artition. I

In Fig. 4 of'the awings I have shown a further modification of the block, in which the outer plates 31 are formed with flat outer surfaces 32 .and with corrugated inner surfaces. The inner plates 34 are in the present instances formed with, both their surfacescorrugated, the arrangement being such that when the blocks are assembled, as shown, diamond shaped air spaces 36 in staggered relation areformed between the plates. All

. the opposing faces of the platesare covered with paper or fabric as before. The plates are separated, as before described, by pieces y of felt orlike material 37 placed between their lar'to those already described. The figure is,

nearest lanes as shown. a

The b ock shown inFig. 5 of thedrawings is similar to that already shown in Fig. 1, except that it has afewer number of intermediate plates 13, its. outer plates 12being simiintroduced to show the means of fastening the block-to a wooden stud 42, this being. accomplishedfby nails "43 through one or more of the plates 12 and 13, the head of.

the nail being forced entirely through the outer plate '12, leaving a, broken aperture 44.

the nails asshown in the drawto other and asfirmly secured to the stud 42. ,the preferred forms of the invention which I have described it-will vbe'seen that there are a series of cells or air spacesformed by'the corrugatedipaper .or fabric, and-that the fabric is embedded and the cells incased oneither side by the plastic material. I em- I ploy the term fabric to (include paper, 45

woven material, felt, and other fabrics. In the broader aspects of my invention it Wlll be seen that it is not essential that there should be projections on each of. the opposing faces of two'plates.

It is obvious that many modifications other than those shown may bemade in mi insulating blocks, and that an efficient bloc ma be made omitting-certain features,'espe-- eoaoes I tached plates of plastic material, each of which is faced by a fabric substantially impervious to plaster secured thereto, at least 7 one of said plates beingformed with, laterally projecting portions extending toward an ad acent plate, whereby air spaces are formed tions extendin' toward an adjacent p ate, and a sheet o fabric placed between said plates and held between said projecting portions, the fabric facing constituting'the lining of the air spaces, substantially for the purposes specified...
